Ahmadiyya founder Mirza Ghulam Ahmad claimed to supersede Muhammad as the final prophet of Islam, which has caused the Ahmadiyya Muslims to be branded as heretics by both Sunni and Shiite Islam and has led to serious persecution over the years. Mirza Ghulam Ahmad also claimed to be Jesus Christ in His second advent. The group claims that Jesus survived his crucifixion and died in Kashmir, India, where He is buried.

Mainstram Muslims do not consider the Ahmadiyyas to be true Muslims. They have been seriously persecuted in Pakistan and elsewhere.
The Ahmadiyya movement is known for its program of translating the Quran from the original Arabic into a variety of other languages (a practice discouraged by mainstream Islam).

Muslim apologist Ahmed Deedat (1918-2005), who publicly debated evangelical apologist Josh McDowell on the subject of Christ’s crucifixion in 1981, was an adherent of Ahmadiyya. (Dr. Anis Shorrosh also debated Deedat on "The Qur’an or the Bible: Which Is God’s Word?" — see resource links below)
